Cov ntsiab lus alloying no tuaj yeem hloov kho qhov kub ntawm forging vim lawv cuam tshuam rau theem kev hloov pauv tus cwj pwm thiab cov tshuaj tiv thaiv eutectoid.
4. Khoom Thickness:Lub thickness ntawm titanium tivthaiv yog forged tuaj yeem cuam tshuam cov cua sov thiab cua txias thaum lub sij hawm forging txheej txheem. Thicker Cheebtsam yuav xav tau kub dua kom ua tau raws li qhov xav tau metallurgical zog uniformly.
Optimal Forging Temperature Range rau Titanium
Qhov zoo tshaj plaws forging kub rau titanium alloys feem ntau nyob ntawm 1650 degree F (900 degree) thiab 1850 degree F (1000 degree). Txawm li cas los xij, qhov ntsuas kub no tuaj yeem sib txawv raws li cov xwm txheej tau hais los saum toj no, thiab nws yog qhov tseem ceeb uas yuav tsum xav txog lawv thaum txiav txim siab txog qhov tshwj xeeb rau ib daim ntawv thov.
Qib-specific Forging Temperatures
Cia peb tshawb nrhiav qhov kub ntawm forging rau ob qib nrov ntawm titanium:
1. Ti-6Al-4V (Qib 5):Forging Ti-6Al-4V feem ntau yuav tsum muaj qhov kub ntawm 1650 degree F (900 degree) txog 1750 degree F (950 degree ). Txawm li cas los xij, qhov ntsuas kub yog nyob ntawm ntau yam, xws li qhov xav tau microstructure, tivthaiv thickness, thiab cov alloy muaj pes tsawg leeg.
2. Kev lag luam Pure Titanium (Qib 2):Kev lag luam ntshiab titanium feem ntau yog forged nyob rau hauv qhov kub ntawm 1750 degree F (950 degree) txog 1850 degree F (1000 degree). Ntxiv dua thiab, qhov kub thiab txias yuav txawv nyob ntawm seb cov khoom xav tau thiab cov qib tshwj xeeb muaj pes tsawg leeg.
Cov txiaj ntsig ntawm Forging Titanium
Forging titanium Cheebtsam muaj ntau qhov zoo dua lwm cov txheej txheem tsim khoom:
